Abstract

Disclosed are adjustable pliers where the pawl mechanism can be engaged or disengaged to adjust a jaw gap of the pliers. The pawl mechanism can be disengaged either by rotating the handles so as to cause a tab to engage a pocket, and/or by lifting upward on the handles to disengage the pawl teeth from corresponding teeth in a slot of one of the handles. The pliers are therefore advantageous because they do not require a button or lever to adjust the jaw gap, and can therefore be adjusted easily.

Description

Adjustable pliers

The present invention relates to pliers. More specifically, the present invention relates to pliers that can be adjusted by the force applied to the pawl mechanism of the pliers.

Pliers are a commonly used hand tool for grasping the grips of many different types of workpieces (such as bolts, nuts, pipes, etc.). The pliers usually include two handles, each of which has a jaw rotatable about a pin that connects the two handles together. The jaws clamp the workpiece, and the handle is used for leverage and clamping to apply force to the workpiece. For example, the pliers can then be turned to insert or remove threaded workpieces, or to pull axially outwards in order to remove unthreaded workpieces, such as nails.

Many pliers are adjustable at the connecting pin. For example, one of the handles can include a slot, and the pin can be inserted through the slot and can move in the slot. For example, when the pin is located at a lower position in the slot, the distance between the jaws is larger, and the pliers can be used for larger workpieces. When the pin is located at a higher position in the slot, the distance between the jaws is smaller, and the pliers Can be used for smaller workpieces. The pawl can engage corresponding teeth in the handle of the pliers to maintain the position of the pawl within the slot, and a button or lever can be used to remove the pawl from the teeth and allow adjustment of the pliers.

The invention broadly includes pliers that can be adjusted by applying a force to the pawl mechanism of the pliers. For example, the pliers can be adjusted by turning the handle outward so that the tabs in the detent mechanism engage the pockets in one of the handles, thereby disengaging the detent mechanism and allowing the handle to be adjusted. In some embodiments, the pliers can be disengaged by lifting up on one handle and removing the pawls from the corresponding teeth. In this way, the pliers do not require buttons or levers to adjust the jaw gap, so the pliers can be adjusted.

For example, an embodiment of the present invention broadly includes pliers including a first handle; a second handle having a groove defined therein, the groove including groove teeth; a coupling member that connects the first handle and the second handle to Together, and allows the first handle and the second handle to rotate around the coupling member; and a detent mechanism, which is connected to the coupling member, and includes detent teeth that mesh with the slotted teeth. The pawl mechanism also includes a roller and a tab around which the tab rotates. At least one of the first handle and the second handle includes a pocket portion that receives the tab to disengage the pawl teeth relative to the slot teeth.

Embodiments of the present invention also broadly include pliers including a first handle; a second handle having a slot defined therein, the slot including slotted teeth; a coupling member that connects the first handle and the second handle together And allow the first handle and the second handle to rotate relative to the coupling member; and a detent mechanism that is connected to the coupling member and includes detent teeth that mesh with the slotted teeth. The pawl mechanism also includes a roller and a tab around which the tab rotates. At least one of the first handle and the second handle includes a pocket portion that receives the tab to disengage the pawl teeth relative to the slot teeth. The ratchet teeth can be removed from the slot teeth by the force applied to the ratchet mechanism perpendicular to the direction in which the slot extends.

Embodiments of the present invention also broadly include pliers including a first handle; a second handle having a slot defined therein, the slot including slotted teeth; a coupling member that connects the first handle and the second handle together And allow the first handle and the second handle to rotate relative to the coupling member; and a detent mechanism that is connected to the coupling member and includes detent teeth that mesh with the slotted teeth. The ratchet teeth can be removed from the slot teeth by the force applied to the ratchet mechanism perpendicular to the direction in which the slot extends.

Although the present invention allows many different forms of embodiments, the preferred embodiments of the present invention shown in the drawings and described in detail herein should be understood as follows, that is, the present disclosure is considered as a principle example of the present invention And is not intended to limit the broad aspects of the invention to the illustrated embodiments. As used herein, the term "present invention" is not intended to limit the patentable scope of the present invention, but is used for discussion of exemplary embodiments of the present invention for explanatory purposes only.

The present invention broadly includes adjustable pliers, in which the detent mechanism can be selectively engaged or disengaged to adjust the jaw gap of the pliers. For example, the pawl mechanism can be detached from the handle using a tab and pocket mechanism. In this embodiment, at least one of the handles can be turned outward to engage the tabs in the pawl mechanism with the pockets in one of the handles, thereby selectively disengaging the pawl mechanism and allowing adjustment of the handle. In addition to or as an alternative to the above, the detent mechanism can be disengaged by lifting up on one handle to remove the detent from the corresponding teeth in the slot. These pliers are therefore advantageous because they do not require buttons or levers to adjust the jaw gap, so they can be adjusted.

As shown in FIG. 1, the pliers 100 may include a first handle 105 and a second handle 110 that are connected together and can be rotated around the coupling member 112. The first handle 105 and the second handle 110 may respectively include: a first grip 115 and a second grip 120, while using the pliers 100, a user may grip the first grip 115 and the second grip 120; and The first transition point 125 and the second transition point 130 extend from the grip 115 and the grip 120 and are connected to the first base 135 and the second base 140. The first jaw 145 and the second jaw 150 may extend from the first base 135 and the second base 140, respectively, and serve as working ends of the pliers to clamp the workpiece and apply torque or axial force to the workpiece.

The coupling member 112 may be inserted through the hole 155 in the first handle 105 and through the slot 160 in the second handle 110. The slot 160 may include teeth 162 that engage corresponding teeth of the detent mechanism 165, as discussed in more detail below. For example, the pin 170 and the elastic member 175 can bias the pawl mechanism 165 to engage with the teeth 162 and adjust the pawl mechanism 165 to increase or decrease the jaw gap when the user adjusts (ie, the Tactile indication at different locations of the maximum available distance between The coupling member 112 may be connected to the pawl mechanism 165 through the fastener 180 and the washer 185.

Referring also to FIGS. 2A and 2B, the forceps 100 may include a detent mechanism 165 that engages the slotted teeth 162 when in a desired position. The pawl mechanism 165 may include: a roller 190 that serves as a rotating base of the pawl mechanism 165; and a tab 195 that is connected to the roller 190. The pawl mechanism 165 may also include pawl teeth 196 connected to the slot teeth 162 to maintain a desired position.

When the user wishes to adjust the jaw gap of the pliers 100, the user can open the handles 105, 110 of the pliers 100 so that the tab 195 engages the pocket 197 of the first handle 105 or the second handle 110, so that the pawl mechanism 165 is removed from The groove 162 is disengaged. For example, as shown in FIG. 2B, the rotation of the first handle 105 or the second handle 110 causes the tab 195 to abut the pocket portion 197, as shown in FIGS. 3A and 3B; further rotation of the handles 105, 110 causes the tab 195 to further Push against the bag portion 197 to provide a force against the biasing force of the elastic member 175. In doing so, the rotation of the handles 105, 110 causes the tab 195 to engage the pocket portion 197 and push the pawl teeth 196 outward to disengage the pawl mechanism 165 from the slot teeth 162. Then, the user can adjust the position of the first handle 105 relative to the second handle 110 to increase or decrease the jaw gap (ie, the two jaws 145 determined by the relative positions of the first handle 105 and the first handle 105, Gap between 150). In doing so, the user can adjust the jaw gap to fit workpieces of different sizes without pressing a button or lever on the pliers 100.

Referring also to FIGS. 4, 5A, and 5B, in one embodiment, the pliers 100 may include a mixing pawl mechanism 202 that can disengage the pawl teeth 196 from the slot teeth 162 to allow adjustment of the jaws gap. As shown, by turning the first handle 105 or the second handle 110 to engage the tab 195 with the pocket 197, as described above, or simply by pulling upward on the mixing pawl mechanism 202, the pawl teeth 196 are removed from The slotted teeth 162 are removed to disengage the mixing pawl mechanism 202.

For example, FIG. 5B shows a way in which the mixing pawl mechanism 202 can be pulled upward to disengage the pawl teeth 196 from the slot teeth 162. As shown, the coupling piece 112 of the mixing pawl mechanism 202 can move in the upward direction within the groove, resisting the bias of the elastic member 175, so that the mixing pawl mechanism 202 is removed from the groove teeth 162 and allows adjustment混爪爪机构202. Alternatively or in addition to the above, by rotating one or both of the first handle 105 or the second handle 110, the mixing pawl mechanism 202 can be disengaged so that the tab 195 engages the pocket portion 197, as described in more detail above Discussed.

Similar to FIGS. 1 to 5B, the pin 170 may be elastically biased by the elastic member 175 located in the lift release pawl mechanism 207. As shown in the figures, FIGS. 6 and 7 show a lift release pawl mechanism 207 that allows adjustment of the jaw gap by pulling upward on the first handle 105 or the second handle 110. For example, to adjust the jaw gap, the user may hold the second handle 110 and pull upward on the first handle 105 against the biasing force of the elastic member 175. An upwardly applied force may be applied to the first handle 105 perpendicular to the direction in which the slot 160 extends to disengage the pawl tooth 196 from the slot tooth 162, as shown in FIG. Thereafter, the user can adjust the position of the first handle 105 relative to the second handle 110, thereby adjusting the jaw gap.
